Hi guys,

After trying to find out as much info that I could to fit a heated screen into my son's Fiesta, we have now hit a brick wall. So, I'm wondering whether anybody has successfully fitted one and if so can they point me in the right direction. So this is where we're up to so far:

We have had the heated screen fitted into a 2004 (54plate) Mk6 Fiesta Flame 1.4 Petrol. Unfortunately we were not lucky enough to find any wiring behind the pillar covers. So, we set about sourcing the various bits that we needed.

I fitted a double switch (front and rear) in place of the existing rear heated screen switch. The connector was wired for both switches, which I took to be a good sign. Next, after purchasing cable that was man enough to handle the current for the screen, I ran a feed to both sides of the screen and connected each of them to a 32A fuse. From the fuses I then connected those to pin 5 of a Ford 70A relay (which I have mounted into the fuse box)

I connected both of the earth tags on the screen to the pillar earth points.

The next job was to get power to the relay which I did by running a cable from the FH 60A terminal in the engine bay fusebox and connected that to pin 3 of the relay.

Pin 1 of the relay is the supply from Fuse 38 (Ignition) which I spliced into near the fusebox (that took some tracing!!), and this is also connected to one side of the switch (pin5)

Now, this is where the brick wall is. The other side of the switch (pin 8) and pin 2 from the relay go to the GEM. I have looked at the GEM and there are no wires in the connecting loom from the switch (although the switch connection has the wire), nor (obviously) is there on from the relay. I understand that the GEM would control the timing that the screen was on etc.

So, I have a question, would I be able to piggy back onto the heated rear screen GEM connections and understand that the screen would/may only work if the heated rear window is switched on? Or is there another way round wiring it all in but bypassing the GEM, but still being able to use the original switch?

We really want to try to get this to work as my other son has just bought, yes you've guessed it, a Fiesta Flame without a heated screen!

Apologies for a long winded post, and hope that it makes sense to someone.

Cheers

Paul

 

cant you just run a wire from relay pin 2 to the gem module connector pin 12 ?

I have considered this but have no idea whether or where I can get the connectors to fit into the terminal block

i would go to scrap yard and have a connector block cut off, and use connector and wire from that. 

Aye, good idea!

Maybe you need a GEM which is equipped with heated windscreen
